Re: Re: Re: And they´re of! 6 more month of lovley rumors!
Relatively speaking, yes the Altivec unit would add a larger % power draw on a G3 than on a G5, but in absolute terms I think the L2 cache draws about the same amount of power.
Except perhaps on the G5 it is nearly impossible to saturate the RAM bus without Altivec. So yes, the implication that has is that I don't think the G3 can saturate it's system bus (probably a really big reason why Apple hasn't upgraded the iBook to DDR Ram). In getting bit to the screen, the video card does mean more than the CPU, but there are specific tasks that can't be done on the GPU, and those will be faster on a machine with a G4 than a G3. And pretty much anything that talks to Quicktime will be faster on a G4 than on a G3 (which is probably more than you think).
No big deal. It's not that it isn't a nice thing to say, it's just something you usually say to a girl

Yes, I was wrong, after looking it up it was just a rumor. But still, it doesn´t sound right to compare a G3 and a G5 when it comes to power draw. I don´t have the facts but I picture that Altivec makes more difference (when it comes down to total power draw) on G3 than on G5. Right, no?

Again, I am wrong. Yes, OSX does use Altivec. BUTdoes it make a big difference? Again I picture that the mojor factors that make OSX faster is RAM, Cache and a good 3D card. Right, no?

You will have to exuse my bad english, I thought that it was a nice thing to say. Sorry
